Anti-Aliasing Border of Icons

       Provided is a technique for the creation of graphical
interface icons with an improved, innovative appearance.

      PROBLEM: When using current tools for creating icons to be used
in a graphical interface, we are limited by the number of pels that
can be contained in a bit map or icon file.  This puts limitations on
the creativity of the graphic designers working with the tools, which
affects the appearance of the icons.  In the past, we have been
limited to 32 x 32-bit maps and 16 colors due to hardware constraints
of VGA terminals.

      SOLUTION: Anti-aliasing has been used for the creation and
display of text in a computer environment but not for icons. This
technique allows for more readable text which improves both the speed
and accuracy of the reader, by softening the edges of the letters,
giving them a more rounded, natural look.  Anti-aliasing is
accomplished by using lighter shades of the color used for the letter
(or icon) to provide an implied border which results in a much softer
look than a harsh outline border of one or two pels.  You don't draw
in the border all in one color; you "shade" in it using the lighter
colors around the edges.  For example, for a black letter, the
anti-aliasing would be provided with various shades of gray.

      With hardware now providing higher resolution which requires
the 64 x 64-size for icons, we can now provide icons with this
anti-aliasing technique by utilizing...
